How do you stop a baby in the backseat from fussing? One mom discovered that turning on Katy Perry’s Dark Horse instantly turns her daughter from tears to cheers.

The adorable Gerber-faced baby is whining and crying but as soon as the music starts her face turns to elation and she pumps her hands in the air. This girl’s American Idol–worthy dance moves were caught on camera and the footage is going viral on YouTube.

YouTube user Eva Baker posted the video yesterday and it has already been viewed nearly a half-million times.
